Abstract

Quantum Dots are man-made artificial atoms that confine electrons to a small space. As such they have atomic-like behavior and enable the study of quantum mechanical effects on a length scale that is around 100 times larger than the pure atomic scale. Quantum dots offer application opportunities in optical sensors, lasers, and advanced electronic devices for memory and logic. This seminar starts with an overview of wavelike and particle like properties and motivates the existence of quantum mechanics. It closes the quantum mechanics point of view with these new fascinating artificial atoms.

Quantum Dot Lab version 1.x ran NEMO-3D. Starting from version 2.0, the underlying engine is NEMO 5, a code under development in the research group of Gerhard Klimeck.

Bio

Gerhard Klimeck is the Technical Director of the Network for Computational Nanotechnology at Purdue University and a Professor of Electrical and Computer Engineering since Dec. 2003. He was the Technical Group Supervisor for the Applied Cluster Computing Technologies Group at the NASA Jet Propulsion Laboratory. His research interest is in the modeling of nanoelectronic devices, parallel cluster computing, genetic algorithms, and parallel image processing. Gerhard developed the Nanoelectronic Modeling tool (NEMO 3-D) for multimillion atom simulations and continues to expand NEMO 1-D. Previously he was a member of technical staff at the Central Research Lab of Texas Instruments where he served as manager and principal architect of the Nanoelectronic Modeling (NEMO 1-D) program. Dr. Klimeck received his Ph.D. in 1994 from Purdue University and his German electrical engineering degree in 1990 from Ruhr-University Bochum. Dr. Klimeck's work is documented in over 130 peer-reviewed publications and over 200 conference presentations. He is a senior member of IEEE and member of APS, HKN and TBP.
